IMPROVEMENT IN GRATES.

Specification forming part of Letters Patent No. 170,612, dated November30, 1875; application filed November 9, 1875.

To all whom it may concern:

Be it known that I, GEORGE WELLHOUSE, of the city of Akron, county ofSummit and State of Ohio, have invented an Improvement in Stove-Grates,of which-the following is a specification:

My invention relates to that class of grates used in coal-burningheating-stoves and my object is to construct a shaking-grate providedwith a means of removing olinkers, slate, and other unconsumedsubstances, without dumping the grate or disturbing the fire. Iaccomplish this by constructing the grate with an opening at or near thecenter large enough for the removal of olinkers, 850., and providingthis opening with a door opening downward, which, when closed, shallform a part of the grate, and released or held in place by a selfactinglatch.

In the accompanying drawing, Figure 1 is a plan of a grate embodying myinvention and the supporting stove-plate, and Fig. 2 a cross-section ofthe same at the line a: w.

A is the grate, consisting of an outer rim and short bars M, projectinginward. This grate rests, at two points within the plate B, upon thelugs O G, which project from the bottom of the plate B, under the rim ofthe grate A. From the front of the grate an arm extends under the plate,through which is a mortise, and a tenon from the bottom of theshaking-plate D enters this mortise, and is held in place by a bolt, '6,thus furnishing the third support for the grate. The tenon of the plateD moves in a curved slot in the plate B, (indicated by dotted lines atD,) thus permitting a shaking motion to the grate. The grate A is madeconcave, to cause clinker, 850., to descend to the center thereof.Within the opening between the ends of the bars it is a door, E, of theshape shown. From the back of this door an arm extends into a recess inthe grate at- F, and, by means of a pin, forms a hinge for the door atthe. point K, and the end of this arm rests upon the shoulder of thecatch G. This catch G swings upon a pivot, b, and is so arranged as toswing forward when free, and engage the extremity of the arm of the doorE. I

By pressing back the catch G with the poker the door falls down, asindicated by dotted lines at E, leaving free the opening in the grate,through which the olinkers, 850., are removed by a hooked poker. Thedoor being swung upward is again caught by the catch G and held inplace.

Having thus described myv invention, I claim- The combination, in astove-grate, of a rim adapted to rotate for shaking out the ashes, andhaving inwardly-projecting arms 2' and recess F, with the drop-plate B,pivoted in said recess, and having a rearwardlyprojeeting arm and thepivoted gravitating-catch G, substantially as shown and described, forthe object herein set forth.
